Chromatographic Behavior of Cryptand[2,2] Modified Resin on Metal Cations
Moo-Yul Suh*, Tae-Yoon Eom, In-Suk Suh, Si-Joong Kim
Cryptand[2,2] was grafted to low crosslinked styrene-divinylbenzene copolymer by substitution reaction with chloromethylated styrene-divinylbenzene copolymer. This resin was stable in concentrated acid and base, and showed a good resistance to heat. The pH, time, and concentration dependence of the adsorption of metal ions by this resin were studied. Studies on the chromatographic separation of lanthanides, Cu2+ and UO22+ were also carried out with various eluents. These studies demonstrate that this resin has the applicability to the preconcentration and separation of metal ions.
